3 Claims.

This invention relates to wire bound box closing tools.

It is one of the objects of this invention to providenovel, improvedwire bound box closing tools so constructed that as a Wire bound box isclosed and one looped end of a wire binding the box together is drawnthrough the other looped end of the wire and crimped downwardlytherefrom, the wire can be tauth tensioned as the crimp is being made.

The objects and advantages of the invention will more fully appear fromthe following description made in connection with the accompanyingdrawings wherein like reference characters refer to the same or similarparts throughout the various views and in which:

Fig. 1 is a perspective view showing a portion of a wire bound box witha tool embodying the invention in use for securing one of the wirebindings of the box.

Fig. 2 is a view in side tool illustrated in Fig. 1, certain of theparts being shown in one position in full lines and in thesecondposition in dotted lines. f

Fig. 3 is a plan view of the tool shown in Fig. 2; and

Fig. 4 is a view in side elevation illustrating a slightly difl'erentembodiment of the invention.

Referring first to the embodiment of the invention shown in Figs. 1, 2,and 3, there is illustrated a wire bound box closing toolincluding afulcrum bar 5 having a tapered forward portion 5a terminating in anotched forward end 5b. The rear end of the fulcrum bar 5 forms a handlesection to which hand grips 6 are secured as by rivets 1. One edge ofthe fulcrum bar 5 is straight, and working along this edge of the bar isa hooking bar 8, which curves at its outer edge towards a narrowedforward end, and along the forward portion of the outer edge of thishooking bar 8 a number of notches 8a are out leaving hooking teeth 81)between these notches. A bell crank lever 9 is pivotally connected bythe pivot bolt III to the rear end of the hooking bar 8, and one arm ofthis lever is pivotally connected to the fulcrum bar 5 by means of thepivot bolt H. The remaining arm of the bell crank lever 9 is preferablyof round cross-section, and it projects generally rearwardly from therear end of the hooking bar 8 so that it the fingers of the hand of anoperator for actuation of the lever while the same hand holds the handleportion and hand grips 6 of the fulcrum lever 5. Forwardly of the pivotbolt in a pair of links l2 located at opposite sides of the hooking canbe readily grasped by lever 8 are pivotally connected thereto by theelevation showing the also have a lateral Wall [5 reinforced terminatesin a pivot bolt l3, and these links are also pivotally connected to thefulcrum bar 5 by a pivot bolt M.

It will be seen that the hooking lever 8, as the bell crank lever 9 isswung, will have a longitudinal sliding movement relative to the fulcrumbar 5 and that, during the first part of the movement of the hooking bar8 from the full line position shown in Fig. 2 to the dotted lineposition there shown, the forward portion of the bar will movement awayfrom the fulcrum lever 5.

The manner of use shown in Fig. 1. portions of a wire of the tooldescribed is In this view there are shown bound box Bincluding a side atits end by a strip It, a top I! reinforced at its end by a strip 18, andan end wall l9. One of several wires binding the box together is shown.This wire is secured as by staples 2! to the various walls of the box,and it has at one end a therein terminating in a prong 2% which ispounded into the side l5 of the box. At its other end the wire 20 formsa second loop 200, which pronged portion 20d pounded into the top I! ofthe box.

In closing the box B, the loop 200 of a wire, such as the wire 20, iscarried downwardly over the side l5 of the box while the loop 20a iscarried through the loop 200.. The tool described is grasped by the handof the operator as shown in dotted lines Fig. l, whereupon the taperedforward end portion 5a of the loop 26a, and the lower part of the loop200 is engaged in the notch 517 at the forward end of the fulcrum bar.As this is done, the outer portion of the loop 20a is engaged within oneof the notches Ba of the hooking bar 8 so that an adjacent hook 8bcatches the loop 20a. Thereupon, while the hand-grip end of the bellcrank lever 9 is pulled by the operator toward the handle of the fulcrumlever 5, the entire tool is swung downwardly about the lower portion ofthe loop 200 as a fulcrum to not only tightly tension all portions ofthe wire 20, and in particular the loop 20a thereof, at the same timethat the loop 20a is being crimped downwardly over the lower portion ofthe loop 200. In other words, pressure is applied due to the action ofthe bell crank lever crimp is being made in the loop the wire 20 arevery 20 employed for fulcrum bar 5 of the l tightly secured togetherwhile one looped end portion of the wire is crimped downwardly againstthe other looped end portion of the wire. It is thus possible to verytightly secure the box by the wire 29 while the wire is tensioned sothat no possible play can take place between the top ll of the box andthe side 15 of the box when the various wires holding the box togetherare secured as described. With other wire box closing tools nowvemployed for the purpose, proper tensioning of the wire is not securedat the same time that the crimping of one looped end portion overanother looped end portion of the wire is done, and thus the presenttool has many advantages over tools now in use in securing a tightclosure of wire bound boxes.

Referring now to the tool shown in Fig. 4, this tool includes a fulcrumbar 22, which is constructed generally similar to the bar previouslydescribed, and the bar 22 carries at its rear end hand grips "23. Ahooking bar 24 similar to the bar 8 previously described is provided,andthe rear end of the bar i l-is connected by pivot stud 25 to a bellcrank lever 26 similar to the lever 9 previously described. The bellcrank lever 25 is connected by a pivot stud 2l'to the fulcrum bar 22. AU-shaped keeper 29' is secured by bolts 28 to the hooking bar 2 and'thiskeeper works over the fulcrum bar 22. The operation of the tool shown inFig. 4 corresponds to the operation of the tool shown in Figs. 1, 2, and3 with the exception that in the case of the tool shown in Fig. 4 thehooking bar 24 has merely a longitudinal sliding movement relative tothe fulcrum bar 22 when the bell crank lever 261 is actuated and thehooking bar 24 has no lateral movement relative to the fulcrum bar22during, actuation of the bell crank lever 25. Thetool shown in Figs. 1to 3, due to the lateral movement of the hooking bar 8 relative to thefulcrum bar 5' as the bell crank lever Sis actuated, has some advantagestherefore over the tool shown in Fig. 4. The lateral spreading action ofthe forward part of the hooking bar 8 relative to the fulcrum bar 5tends to, further tension the wire during the swinging movement of thetool shown in Figs. 1 to 3.

It will be seen that a very simple and highly efiicient wire bound boxclosing tool has been provided in accordance with the present invention.

It will of course be understood that various changes may be made in theform, details, arrangement, and proportions of the various parts.without departure from the scope of the present invention which,generally stated, consists in the matter shown and described and setforth in the, appended claims.
